I assume you guys worked it out, but i was setting the droop with the little grub screw (when i first got the car), before i realised that that the part had a square end designed to be a turn buckle so you dont have to fiddle with the grub screw.

Initially i had the turnbuckle screwed all the way in so there wasnt much room for droop adjustment when i was using the grub screw :P
